A common function needed for all the boundary forcing data series is the need to add, edit, view, and compare time series for forcings. Following is a summary of the processes and other time series utilities in EE10. A list of the forcing data is accessed using a LMC on the External Forcing Data menu shown in Figure 1. The number of series that have been generated is shown in brackets. Some of the items in the menu have unique options which are described in on the particular page for that option.
The time series for the external forcing data can be assigned to boundary groups and cells later in the Boundary Condition tab. The display on the right of Figure 1 provides the user with a summary of the current currently assigned boundary groups and input tables, time series.

The user can add and delete series with Add New and Delete. Added series will appear in Select Series, the user can select a series using the drop-down list. The name of a series can be edited in Series Name. Press "Enter" afterward to apply the edit.
View Series 
button will allows the user to plot the series using EFDC_Explorer plotting tool. The user can also choose to plot multiple series and multiple layers in a graph using View Options.
The user can It is able to copy the data from data file files and paste it directly in to into the table as in Figure 4. This table behaves like a Microsoft Excel (c) table where the user can use Shift and Ctrl keys to select multiple cells and includes options like Copy Data, Paste Data, Insert Row, Delete Row buttons as highlighted in Figure 4 .

Columns Format
The format of the data series table can be changed in the Columns tab. The format in here follow the Standard Numeric Format Strings of C#. In this case, F4 is a floating number with 4 decimal digits. The number 4 can be replaced for a different precision value.
